Yarn holder



Oct. 2, 1934. w. P. HORNBUCKLE, JR 1,975,363

- YARN HOLDER Filed Jan. 18, 1952 Patented Oct. 2, 1934 PATENT 4 Claims.

This invention relates to a yarn holder and more especially to a perforated tubular yarn holder adapted to be placed on fiber preparation machinery, such as spoolers, fiy frames, roving frames, speeders, slubbers, and the like for winding thereon yarn and after the yarn is wound onto the tubular member the said tubular member can be removed from its associated structure and placed in a machine for treating the yarn,

such as dyeing, bleaching and otherwise treating the yarn on the tubular member.

Heretofore, tubular members have been inserted on various types of textile machinery for winding yarn thereonto and these textile machines have been equipped with members for holding the tubular member and from which members the tubular perforated member can be removed in a manner similar to the use of the present invention.

Heretofore, slotted collars have been used for holding the perforated yarn holders, but no means have been provided for preventing relative movement between the collars and the perforated yarn holder except that of friction and due to the inaccuracies of the collars with relation to the tubular member certain slippage has occurred and it is an object of this invention to provide means whereby the tubular member and its associated collar may be held in a non-turnable relation during the time the yarn is wound onto the tubular perforated member.

Broadly, my invention contemplates a bobbin having a base and a top insertable into a tubular member with means to insure that no relative movement between the base and the tubular member will occur, with means for confining the base on the bolster while the tubular member may be removed leaving the base of the bobbin mounted on the bobbin gear.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawing, in which 5 Figure 1 is a View of a portion of a spindle, bolster and bobbin of a spinning frame showing certain parts of my invention in vertical section; Figure 2 is an enlarged cross sectional view taken along the line 2-2 in Figure 1;

Figure 3 is an enlarged cross sectional view taken along the line 33 in Figure 1;

Figure 4 is an enlarged elevation of the lower collar onto which the perforated member is adapted to be placed;

Figure 5 is an enlarged elevation of the bushing or top collar adapted to be inserted in the v top of the perforated tubular member.

Referring more particularly to the drawing, the numeral 10 indicates one of the spindles of a spinning machine, and a bolster shoulder 11 is slidably mounted on the spindles 10 and a bobbin support comprising a bevel gear 12 having a hub portion 13 is mounted for sliding movement on spindle 10. Reference character 14 indicates a bolster integral with bolster shoulder 11. The top of spindle 10 is slotted as at 15 for the reception of the fiyer not shown, all of which is conventional structure.

Instead of having the bobbin of wood and made all in one piece, I provide a collar 16 having four slots 1'7 therein and with notches 18 therein for engaging projections 19 on hub 13, so that when collar 16 is dropped onto hub 13, the projections 19 engaging notches 18, will cause collar 16 to be driven at the same rate of speed as bevel gear 12. I provide the perforated member 20 which is ordinarily covered with a fabric 21 and this perforated member 20 has indentations 22 therein adapted to fit into slots 16 to prevent relative movement between perforated member 20 and member 16. Bushing 23 which fits into the top of perforated member 20, likewise, has slots 25 therein into which the indentations 26 in perforated member 20 is adapted to fit.

The indentations 26 and slots 25 in bushing 23 perform no useful function except for the reason that by making both ends of the perforated member 20 with the indentations therein and having both members 16 and 23 slotted, it allows interchangeability of the ends of perforated member 20 so that it is not necessary to determine into which end member 16 is to be inserted before placing, the perforated member 20 on the spinning machine and the like.

A collar 2'7 is secured on bolster 14 to confine base 16 on the bolster. The bobbin turns with relation to the bolster, but collar 27 does not rotate.

In the drawing and specification, there has 100 been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being set forth in the 105 appended claims.

I claim:

1. In fiber preparation machinery having a spindle and a bolster slidably mounted on the spindle and a bobbin gear slidably and rotatably 110 mounted on the bolster, a bobbin having a slotted base member and a slotted top member, means for loosely confining said base member on the bolster, a tubular member into the ends of which the said base and top members are adapted to be fitted, and projections on the interior of said tubular member for engaging said slots in said base and top members.

2. In a yarn holder for fiber preparation machinery, a hollow base memberhaving an enlarged lower portion, said lower portion having radially disposed grooves in the lower end thereof, the base member having longitudinally extending slots open at their upper ends and a tubular yarn holder fitting over the base member and having means in the inside thereof for engaging .said longitudinally extending slots.

3. In a yarn holder for fiber preparation machinery, a hollow base member having an enlarged lower portion, said lower portion having radially disposed grooves in the lower end thereslotted. top member, means for loosely confining the base member on the bolster, a tubular member, into the ends of which, the said base and top members-are adapted to be fitted, and projections on the interior of said tubular member for engaging one of said slots in said base and top members.
